Product Features

Hygger 500W / 800W titanium steel aquarium heater with external controller and digital displays on heater and the controller has a fast heating up speed. It is perfect for using in large fish tanks sized over 60 gallon in cold weather.

Energy-saving heater for aquarium larger than 60 gallons

It takes about 2 minutes to heat 3.5 gallon water up 3°F with this fast heating up aquarium heater. It is more energy-saving than general high power heater with 2 heating modes: MAX heating, ECO heating, because the 2 modes shift automatically according to the D-value between the water temp and set temp.

1. Max heating mode

It means fast heating at full power when heater is used to heat for the first time or when the water temp drops 1°F or more lower than the set temperature.

2. ECO heating mode

It means slow heating to save energy. It only works when the water temp drops off 0.5-1°F than the set temperature.

Safe to use

With built-in thermometer and waterline detector, the heater will automatically shut off when overheating (over 97°F) or not fully submerged (the top of the heater is out of water over 0.8 inch).

Dual digital displays on controller and heater

The digit display on the heater is to show the current water temperature while the digit display on the controller is to show the current water temperature and the set temperature. You can check the water temperature whether on the heater or on the controller display because the digits are synchronized updated.

Fully automatic smart thermostat

It’s very easy to set the temperature on the controller. Just press the “Set” button to choose the temp digits from 70°F to 94°F (only integer value can be chose). The heater will stop heating when the water temp reaches the set temp, and it will restart heating when the water temp is 0.5°F lower than the set temp. The heating mode is MAX heating when the set temp is 1°F or more higher than water temp; And it will be running on ECO heating mode when water temp is 0.5-1°F lower than the set temp.

Suitable for fresh water and marine water

Covered by sturdy plastic guard, and with durable black titanium steel heating element, this fish tank heater has a service life that can last for 3 years or more. It can be used for fresh-water and salt-water fish tanks. The aquarium heater comes with a sturdy clip. And there are 2 strong suction cups on the clip, which makes it easy to install the heater on to the fish tank wall. The fish tank heater can be placed horizontally or vertically, but must be fully submerged underwater.

Directions for Use

1. Please install the heater fully under water, but don’t bury it in sands.
2. Please unplug the heater and wait it to cool down for about 5-10 minutes before water changing or moving the heater.
3. To well install the fish tank heater on to the tank wall, it is suggested to slip the suction cup clip to the top 1/3 of the heater tube.
4. It is suggested to install the submersible heater under water close to the water intake. You can place it vertically or horizontally. Note: Placing it vertically will not take up too much space.
5. Please use wave maker or a circulation pump for the fish tank because good water circulation will help uniform dispersion the heat produced by the heater.

Error Code Explanations and Solutions

Error Code “Er”

Case 1. Automatically shut off when out of water

If you see the error code “Er” on the controller and the heater display, it means the heater is not well installed fully under water, it will automatically shut off.

Case 2. Automatically recover work when fully under water
The heater will automatically work normally after you placing the heater fully under water.

Error code “EH”

Case 1. Automatically shut off when water temp over 97°F.

If you see the error code “EH” on the controller and the heater display, it means the water temp is too hot, it will automatically shut off. But the rest heat of it may make the water temp go up for a little more.

In this case, please wait the water to cool down or you can add some water into the fish tank.
